Solution:
Subject verb agreement + Awkwardness
A: the number of the students is a singular subject and hence, 'have' and 'are' are incorrect verbs for the subject, since clause is illogically used.
B: 'with' is unnecessary, reaching a record high is not correct, awkward sentence structure
C and E: it is suggested that students have reached a record high. In C since clause is illogically used after colon. In E comma is wrongly used before since.
D: subject the number of students agrees with the verb has and hence, the best choice.
